Insect Farming Welfare and Black Soldier Fly Larvae

Black soldier fly (BSF) larvae are farmed at massive scale for animal feed. Insect sentience is uncertain, but precautionary welfare consideration is warranted given the enormous numbers farmed and the conditions under which they are raised and processed.

Key Facts

Black soldier fly larvae are farmed for protein meal to replace fishmeal in aquaculture and livestock feed
Global insect farming produces millions of tonnes of protein annually
BSF larvae are typically killed by immersion in hot water or steam at processing
The question of insect sentience and nociception is scientifically unresolved
Some researchers argue that insect neural complexity warrants precautionary welfare consideration

Welfare Considerations

Whether black soldier fly larvae have subjective experience of suffering is scientifically uncertain. However, the precautionary principle supports minimising potential suffering in systems involving enormous numbers of individuals. Processing methods that achieve rapid death with minimal heat exposure represent a welfare improvement over slow thermal processing, even under uncertainty. The welfare of insects in agricultural contexts is an emerging field that will grow in importance as insect farming scales up.
